tíc mình nha
( 2x - 34 ) . 69 = 0
( 2x - 34 ) = 0 : 69
2x - 34 = 0
2x = 0 + 34
2x = 34
x = 34 : 2
x = 17
(2x-34) . 69 =0
=> (2x -34 ) = 0
2x - 34 = 0
=> 2x =34+0
2x =34 => x= 34:2
x=17
( 2x - 34 ) . 69 = 0
2x - 34 = 0 : 69
2x - 34 = 0
2x = 0 + 34
2x = 34
x = 34 : 2
x = 17
Ta có:(2x-34).69=0 =>2x-34=0 =>2x=34 =>x=34:2 =>x=17
tìm STN x
2x + 69 . 2 = 69 . 4
2x - 12 - x = 0
(x-7) . (2x - 8) = 0
Tìm x
a) 2x + 69 . 2 = 69 . 4
b) 2x - 12 - x = 0
c) ( x + 1 ) + ( x + 2 ) + ... + ( x + 10 ) = 165
c) ( 34 - 2x ) . ( 2x - 6 ) = 0
d) ( 2019 - x ) . ( 3x - 12 ) 0
nhanh nha, mik tick cho
Tìm x :
1) (x - 20) .15 = 0 2) 4 . (x - 7 ) = 4
3) 6 . (x - 12) = 6 4) (2x - 34) . 69 = 0
5) 17 . (x - 9) = 0 6) (x - 40) - 270 = 0
7) 127 + (200 - x) = 217 8) 427 - (x +100) = 227
NHANH GIÚP MÌNH !!!
( 2x - 34 ) . 17 = 0
c) ( 34 - 2x ) . ( 2x - 6 ) = 0
d) ( 2019 - x ) . ( 3x - 12 ) 0
nhanh nha, mik tick cho, giải thik rõ nhé
5 (x - 7) = 0
34 (2x - 6) = 0
( 2x - 34) . 17 = 0
